High-pressure hoses are used in automobile braking systems, air-conditioning systems, sunroof drainage systems, etc., do you know what materials these common high-pressure hoses are made of in cars? As a professional auto hose manufacturer, I will introduce the high-pressure hose materials commonly used in automobiles.
First, Brake hose
The main materials of automobile brake hoses are EPDM and neoprene (EPDM, CR). EPDM is resistant to brake fluid, not resistant to oil, and has good low temperature resistance. CRDM is resistant to brake fluid, oil, and low temperature.
Someone will ask about brake tubing made of material like EPDM need to be changed?
There is no fixed replacement cycle for the brake hose, as long as there is no oil leakage, it does not need to be replaced. The brake oil pipe is used to transmit the brake oil of the car. It is a kind of consumable parts of the car. When a fault occurs, it will naturally affect the braking system of the whole vehicle, and it needs to be replaced in time.
Second, the air conditioning hose
The main materials of automotive air-conditioning hoses are EPDM and chlorinated butyl rubber (EPDM, CIIR). This material has low permeability and high bonding strength with nylon layer
Third, the sunroof drain pipe.
The main materials of common sunroof drainage pipes for automobiles are polyvinyl chloride, EPDM, polypropylene + EPDM (PVC, EPDM, PP + EPDM), PVC is recyclable, low temperature is hard, EPDM is not recyclable, and resistant to low temperature Good performance, PP + EPDM can be recycled, low temperature resistance is good, but the cost is higher.
The above is the knowledge of automobile hoses introduced to everyone. Understanding the materials of high-pressure hoses commonly used in automobiles will help you choose the correct way to overhaul and maintain them, thereby extending the life of the automobile.
